I have not installed them yet. I can triple check...for my own piece of mind. But yes,120. Will that cause a rich idle?
If i understand correctly, these flow air, not fuel. At idle, smaller paj2 will mean richer mixture. At idle... Which will also effect the whole throttle range to some extent.
If so, this explains the unburnt fuel smell in the exhaust at idle. My mixture screws never leaned it out, definitely never came close to stalling even bottomed out.
PAJ#2, controls air just off idle, and all the way thru after that. So, you would be running richer, off idle, until redline. But you could be running so rich, that at idle its still trying to burn the excess fuel.
So put in some 170's, and that should help a lot.
PAJ#1 controls the air at idle. Thats why Cali bikes have a different PAJ#1, than the other 49 state set up.
